Thank you for purchasing one of our products. Please read in-
structions on use in this manual as well as the safety rules
9
given in the attached booklet and follow them carefully to get
the best performance from the plant and be sure that the parts
9
have the longest service life possible. In the interest of custom-
9
ers, you are recommended to have maintenance and, where
necessary, repairs carried out by the workshops of our service
9
organisation, since they have suitable equipment and specially
trained personnel available. All our machinery and systems are
9
subject to continual development. We must therefore reserve
9
the right to modify their construction and properties.

RAINBOW 180 is the latest evolution in inverter technology
11
generators for welding. The most advanced materials and com-
ponents have been used to design and produce it such as:
12
• Main planar transformer with extremely low load loss.
• Electronic auxiliary feeder.
12
• Voltage doubler ensuring precision striking, constant arc and
very low electrical input from the main supply by the welder.
12
• Extremely high frequency power INVERTER with very lat-
est type of IGBT to reduce switching losses to a minimum.
68
• The inverter resists ample current variations (MAX 290V) and
69
can be utilized with very long electric cables (MAX 100 m).
• High electric efficiency (> 0,8).
69
• Selector with 3 weld procedures:
- Basic electrodes with "Hot Start" and "Arc Force" device.
72
- Stainless steel electrodes with special characteristics for
74
a soft arc.
- TIG welding with thermal controlled (TCS) "Lift" type strik-
76
ing reducing tungsten inclusions to a minimum and allow-
ing to also strike on sharp edges.
77-79
• The generator also conforms to all European Union stand-
80
ards and directives in force.
